Acharya Prashant discusses the true nature of the relationship between a parent and a child, emphasizing that a father's duty goes beyond merely fulfilling a child's material expectations. He explains that while a child may bring material desires learned from the world, true love lies in sitting with the child, understanding their mind, and observing their life rather than just buying things from the market. This process of cleansing the mind requires energy, time, and closeness. He notes that as the child matures through this guidance, the parent also grows, leading to a beautiful transformation in their friendship where the child eventually becomes less dependent.
